Finite elements using COMSOL Multiphysics have been used to simulate the edge plasma in a large area capacitively coupled RF reactor. In order to reduce numerical difficulties simplified reactor edge geometries have been used. First results show the importance of electrostatic double layers within this plasma. In addition the non-uniform behaviour of the plasma sheath around convex and ...

Two-generation superconducting coils carrying large current in alternating magnetic fields is very common in electrical applications such as HTS linear motor. So it is meaningful to study the characteristics of coated superconductors in the presence of travelling magnetic field. In this paper, by using the finite element simulation software COMSOL Multiphysics® software, the characteristics of ...

A logic gate performs a certain Boolean logic operation on one or more logical inputs and produces a single logical output. The logic values are either “true” or “false.” Logic gates are bistable devices, that is, they may yield one of these two possible stable outputs. The NAND logic is a universal gate; any logic operation can be performed with various combinations of NAND logics. Many ...

Seals or gaskets that are compressed between walls of a container are important to many industrial applications. Understanding the performance of such seals requires an understanding of the microscopic geometry of the sealing surfaces, because the fluid seeps around the undulations of such surfaces. This paper presents strong computational evidence that the microgeometry of such surfaces depends ...

Single coil actuators are representing one important component of ABB’s medium voltage reclosers. Their performance is strongly influenced by the considered material properties as well as by the electronic control units’ properties that will power the actuator. Therefore, this paper focuses on electromagnetic actuators modeling and simulation in COMSOL Multiphysics®.

Introduction: Type II photodynamic therapy (PDT) is an experimental modality for cancer treatment based on the combined action of a photosensitizing drug (photosensitizer), a special wavelength of light and singlet oxygen (1O2) generation; the cell killing is caused by the reaction of cellular acceptors with 1O2. A mathematical model has been previously developed to incorporate the macroscopic ...

Mechanical product design is crucial in many engineering field and lots of industries. CAE simulation has been widely applied for predicting virtual product design for a few decades to reduce the cost and shorten the design life cycle. Because of complicated geometry, material/geometrical nonlinearity and complex conditions, it is painful to efficiently and accurately simulate and predict ...

A promising method for low cost production of efficient silicon thin film solar cells is the electron beam physical vapor deposition (EB-PVD) of high purity amorphous silicon (a-Si) layers with high deposition rates up to 300 nm/s  followed by crystallization. This study focuses on EB crystallization of deposited a-Si films in the solid phase regime and justifies observed experimental results ...

Numerical simulations applied to blood flow together with the imaging processing advances are a powerful tool in the prevention and treatment of some diseases. The inclusion of real data in the numerical blood flow simulations allows the achievement of more realistic and accurate results. In the literature, these techniques are known as Data Assimilation (DA). We solve a variational DA problem ...
